The accessor output-pane-cached-display-user-info
gets and sets the user-info in the current cached display of the output pane pane.
If pane does not have a cached display, the getter returns nil
and the setter has no effect (but returns the new user-info as per normal Common Lisp conventions).
A value that is set by the setter will be returned by the getter until the cached display is freed by a call to output-pane-free-cached-display, either explicitly or implicitly. Note that this means that calls to start-drawing-with-cached-display and output-pane-cache-display also reset the user-info.
